Petunia plant named ‘Sunrurf Grihuti’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Sunsurf Grihuti’, characterized by its upright to outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; medium-sized pale yellow green-colored flowers with darker yellow green-colored margins and venation; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘SUNSURF GRIHUTI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Sunsurf Grihuti’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact, freely branching and freely flowering Petunia plants with mounding habit and attractive flower coloration.

The new Petunia plant originated from a cross-pollination made by the Inventor in January, 2010 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code name Px5315-03, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code name Px5314-01, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in November, 2010.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since November, 2010 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunsurf Grihuti’. These characteristics in combination distinguish ‘Sunsurf Grihuti’ as a new and distinct Petunia plant:

-   -   1. Upright to outwardly spreading and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Long flowering period.     -   6. Medium-sized pale yellow green-colored flowers with darker         yellow green-colored margins and venation.     -   7. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are more mounding than and not as         trailing as plants of the female parent selection.     -   2. Plants of the new Petunia have larger flowers than plants of         the female parent selection.     -   3. Plants of the new Petunia and the female parent selection         differ in flower color as plants of the female parent selection         have white-colored flowers.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are more mounding than and not as         upright as plants of the male parent selection.     -   2. Plants of the new Petunia have slightly smaller flowers than         plants of the male parent selection.     -   3. Plants of the new Petunia and the male parent selection         differ in flower color as plants of the male parent selection         have white-colored flowers with green-colored margins.

Plants of the new Petunia can also be compared to plants of the Petunia ‘BHTUN31501’, disclosed in U.S. Plant Pat. No. 21,649. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘BHTUN31501’ differed primarily in the following characteristics:

-   -   1. Plants of the new Petunia were more mounding than and not as         trailing as plants of ‘BHTUN31501’.     -   2. Plants of the new Petunia had shorter internodes than plants         of ‘BHTUN31501’.     -   3. Plants of the new Petunia were more freely flowering than         plants of ‘BHTUN31501’.     -   4. Flower throats and tubes of plants of the new Petunia were         smaller in diameter than flower throats and tubes of plants of         ‘BHTUN31501’.     -   5. Plants of the new Petunia and ‘BHTUN31501’ differed in flower         color as plants of ‘BHTUN31501’ had dark red purple-colored         flowers with green-colored margins and dark violet-colored         centers.     -   6. Plants of the new Petunia had longer and thicker peduncles         than plants of ‘BHTUN31501’.
